IOUserClient

Provides a basis for communication between client applications and I/O Kit objects.

Enumerated Types

kIOExternalMethodScalarInputCountMax

Constants to specify the maximum number of scalar arguments in the IOExternalMethodArguments structure. These constants are documentary since the scalarInputCount, scalarOutputCount fields reflect the actual number passed.

kIOUCVariableStructureSize

Constant to denote a variable length structure argument to IOUserClient.
